【摘要】 通过优化设计虽然可以得到TMD系统的最优参数 ,但是结构优化目标函数往往不只一个 ,尽管可以用加权的方法把多个目标函数转化成单个目标函数 ,但如何选取权值没有公认的标准 ;此外 ,实际工程中所实现的结构参数与设计参数总会有误差 ,而这种误差可能会使优化效果变差 ,单纯从最优参数解难以了解变差的程度。为此提出了TMD参数有效域的概念 ,利用参数有效域进行TMD系统设计 ,可以有效提高TMD可靠性 ,进一步促进TMD减振技术的推广使用更多还原

【Abstract】 The optimum parameters of a TMD system can be determined with optimization designing.However,sometimes object functions needed to be optimized are more than one.Although it′s possible to integrate multiobject functions into one object function with weighting method,how to select weighting coefficients is disputable.Besides,there are always errors between the parameters realized in practical engineering and the designed ones which would deteriorate optimization effect.It’s difficult to find out how bad things were from optimum parameters.The concept of effective parametric fields is presented.To design TMD system with effective parametric fields can effectively improve reliability of the TMD system,therefore promote the spread and utilization of TMD shock-absorption technique.更多还原
